The special rotor structure of the axial PM bearingless flywheel machine(APM-BFM) makes its critical speed more easily affected at high speed, but there are few studies on dynamics, especially under load conditions. In paper, model analysis study APM-BFM is carried out. First, mechanism used to explain and system analyzed in conjunction with experimental prototype; centroid deviates from center...

Flywheel-based resistance exercise (RE) attenuates muscle atrophy during hindlimb suspension. We have previously shown that protein synthesis is elevated in response to RE, but the effect on protein degradation, cell proliferation, or apoptosis was not investigated. We hypothesized that, in addition to affecting protein synthesis, RE inhibits processes that actively contribute to muscle atrophy...

Di tengah maraknya isu keterbatasan sumber daya alam, perkembangan teknologi dan perindustrian serta pertumbuhan penduduk yang pesat membuat kebutuhan akan listrik terus meningkat, termasuk nelayan Krueng Aceh melakukan usaha penangkapan ikandengan sistemlight fishing. Peneliti penelitian terapan mengenai Generator memanfaatkan efek Flywheel, dengan tenaga baterai 36/48 Volt, dihubungkan motor ...

The objective of this study was to compare (i) effects a flywheel and free-weight resistance training program; (ii) performing lateral frontal split squats as part flywheel-resistance program on jumping performance, the 5–0–5 change direction test time, one-repetition maximum (1RM) back squat in soccer players. Twenty-four male amateur players participated were randomly equally assigned one thr...

The objective of this study was to evaluate the changes in the portal vein cross-sectional area (PV CSA) and flow during a stand test associated with orthostatic intolerance. Eighteen subjects underwent a 90-day head-down tilt (HDT) bed rest at 6 degrees: 9 controls (Con) and 9 with flywheel exercise countermeasures (CM). At post-HDT, nine subjects (5 CM, 4 Con) were tolerant, and nine were int...

Flywheels can exert torque that alters the Station's attitude motion, either intentionally or unintentionally. A design is presented for a once planned experiment to contribute torque for Station attitude control, while storing or discharging energy. Two contingencies are studied: the abrupt stop of one rotor while another rotor continues to spin at high speed, and energy storage performed with...

This paper presents experimental results on an innovative electric driveline employing a kinetic energy storage device as energy buffer. A conceptual division of losses in the system was created, separating the complete system into three parts according to their function. This conceptualization of the system yielded a meaningful definition of the concept of efficiency. Additionally, a thorough ...

Energysaving systems can be classified into different types: hydraulic, electric and mechanical system using flywheels. Flywheels have been used to achieve smooth operation of machines. Now a days flywheels are complex constructions where energy is stored mechanically and transferred .Most engineers have used the concept of storing kinetic energy in a spinning mass to smooth their operation. Th...

To extend the operating speed range of a conventional configuration of FESS (flywheel energy storage system), an additional DC-DC boost converter is required between the machine and grid side converters to regulate the output voltage. This paper presents a new FESS based on three-phase boost inverter topology. The proposed system facilitates voltage boost capability directly in a single-stage. ...
